No, it hasn't. And it won't be until the game is completed. If we think that the developer will be going down the path of Acting Lessons, then that would be one possibility. However, I believe that the warning given by Jill at the very beginning of the game is a red herring, a thumb in the eye to those of us who found it difficult (if not impossible) to finish Acting Lessons, rather than a real warning of dire events to come. There will be drama, of course, and heartache. But deaths? I seriously doubt it. I strongly believe that DrPinkCake has gotten that out of his system.
Again, though, I will only be proven right or wrong by the game being completed.
